Ingo Molnar released a new patchset titled the 'Modular Scheduler Core and Completely Fair Scheduler'. He explained, "this project is a complete rewrite of the Linux task scheduler. My goal is to address various feature requests and to fix deficiencies in the vanilla scheduler that were suggested/found in the past few years, both for desktop scheduling and for server scheduling workloads."

Scientists are getting better at collaboration, resulting in less error from consensus.

This paper proves one thing: Science can't be trusted for producing truth. Ask the ~100million people who were exterminated last century by people and governments who used "science" as their rationale.

I wouldn't call this OS stuff "science" in the same way, writing software algorithms is more akin to engineering, since computers are problem domain artificially limited by the capabilities of the hardware.

That said, there's nothing wrong with going back and refactoring something occasionally to see if there's a better way to do it.

I'd say at least half the code I write gets tossed on the trash heap. Sometimes because of an initial misunderstanding of the problem, definitely because writing the code is a part of learning the problem.
